cds-question@unistra.fractive-galactic-nucleiradio-sourcesActive galactic nuclei (AGNs) can be divided into two major classes, namely radio-loud and radio-quiet AGNs. A small subset of the radio-loud AGNs is called blazars, which are believed to be unified with Fanaroff-Riley type I/II (FRI/II) radio galaxies. Following our previous work (Fan et al., 2011RAA....11.1413F), we present a sample of 2400 sources with measured radio flux densities of the core and extended components. The sample contains 250 BL Lacs, 520 quasars, 175 Seyferts, 1178 galaxies, 153 FRI or FRII galaxies and 104 unidentified sources. We then calculate the radio core-dominance parameters and spectral indices, and study their relationship. Our analysis shows that the core-dominance parameters and spectral indices are quite different for different types of sources. We also confirm that the correlation between core-dominance parameter and spectral index exists for a large sample presented in this work.2019RAA....19...70Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/other/RAA/19.70CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/other/RAA/19.70https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/other/RAA/19.70http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/other/RAA/19.70https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/other/RAA/19.70https://vizier.iucaa.in/viz-bin/votable?-source=J/other/RAA/19.70http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/other/RAA/19.70GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapRadiodefaultJ/other/RAA/19.70/table1for all the sourceszRedshiftsrc.redshiftfloatrecnoRecord number assigned by the VizieR team.
